Embodiment 1

[0031] Embodiment 1: a kind of cleaning process before painting, comprises the following specific steps:

[0032] Step a, heat treatment: turn on the pre-degreasing tank and the display on the degreasing tank in turn, the water heater exhaust fan, the water heater heat exchange pump and the pre-degreasing solenoid valve, adjust the temperature according to the season, open the air valve, and set the temperature in summer. Between 25-40°C, set the temperature between 40-60°C in winter, maintain the pressure gauge value on the pre-degreasing tank and the degreasing tank at 0.2-0.4 as a whole, put the workpiece into the pre-degreasing tank and the degreasing tank Preheat the temperature one hour before;

[0033] Step b, pre-degreasing treatment: carry out pre-degreasing treatment in the pre-degreasing tank, the temperature of the bath is maintained at 25-50°C, the concentration of the bath is maintained at 13-18 points, the pressure of the water pump is maintained at 0.08-0.16Mpa...

Description

technical field [0001] The invention relates to the technical field of painting, in particular to a cleaning process before painting. Background technique [0002] Coating is an important link in the modern product manufacturing process. The quality of anti-rust and anti-corrosion coating is one of the important aspects of the overall quality of the product. The appearance quality of the product not only reflects the protection and decoration performance of the product, but also an important factor that constitutes the value of the product. Coating is a systematic project, which includes three basic processes: treatment of the surface of the object to be coated before coating, coating process and drying, as well as designing a reasonable coating system, selecting suitable coatings, determining good working environment conditions, and carrying out Important links such as quality, process management and technical economy. [0003] At present, the Chinese patent with publicat...
